Abstract
|
|
|
|
| The microstructures and microhardness of pure Ni processed by high-pressure torsion and their evolution upon dynamical heating from room temperature to 200 degrees C at a heating rate of 20 degrees C/min were investigated. The annealing resulted in further refinement of grains, formation of more fraction of high-angle grain boundaries (GBs), modification of state of GBs and ordering of dislocations. As a result of the microstructural optimization, the microhardness of the material was increased but not decreased after the dynamical heating. (c) 2006 Elsevier B.V. All rights reserved. |
